I believe this is a valid question for this mailing group.
It would be nice
to know where web mail fits into the S/MIME picture (if not, will it
ever?...) and if there will be any future use of encryption
services for
this type of internet messaging. At least I myself am interested.
S/MIME is not incompatible with Web mail. It is purely an implementation
issue for the Web mail providers.
It is not a topic for this group unless Web mail providers discover
some specific feature that is essential or highly desirable for
Web mail support and want to raise it.
